EU Parliament postpones a vote on crypto regulations following backlash over a leaked provision banning proof-of-work cryptos like bitcoin over energy concerns
A leaked draft has drawn criticism for including a provision that sought to ban the use of cryptocurrencies that rely on proof-of-work.
Context & Ripple Effects
The European Union's flagship Markets in Crypto Assets framework hit turbulence when a leaked draft surfaced containing a provision that would have banned proof-of-work cryptocurrencies like bitcoin over their energy consumption, triggering enough backlash that the Parliament postponed its scheduled vote.
The episode became a turning point in how Brussels treats crypto's energy footprint: within weeks the offending wording was stripped out and a new vote date set [[a:976709]], the committee formally rejected the proof-of-work restriction [[a:976897]], and by autumn the economics committee approved a MiCA bill that regulates mining rather than banning it [[a:983714]].
First-order effects
- Bitcoin and other proof-of-work networks operating in the EU get an immediate reprieve — no vote is taken on rules that would have outlawed their consensus mechanism.
- The Parliament's legislative calendar slips, delaying clarity for crypto firms awaiting the MiCA framework.
Second-order effects
- Industry critics learn that public backlash against leaked text can force removal of the most aggressive provisions, raising the cost of drafting hard bans into EU crypto law.
- With the ban language dropped, regulatory attention pivots toward managing mining's energy use inside MiCA rather than excluding proof-of-work assets outright.
Third-order effects
- If the pattern holds, EU crypto legislation converges on supervised compliance — licensing, disclosure, and energy reporting — instead of technology bans, as later confirmed by the committee-approved MiCA bill and the provisional Anti-Money Laundering deal requiring user due diligence across all crypto companies.
- Energy consumption becomes a standing axis of crypto regulation in Europe, shaping where miners locate and which consensus mechanisms exchanges list.
The trend: EU crypto rulemaking is shifting from attempted outright bans of proof-of-work toward managed regulation of mining and market conduct under frameworks like MiCA.
